2 Putting the Analyzer into Operation
This section describes the basic steps to be taken when setting up the analyzer for the
first time.
Simple measurement examples are provided in Chapter 5, "Performing Measure-
ments", on page 64; for a description of the operating concept refer to Chapter 4,
"Operating the Instrument", on page 38. For all background and reference informa-
tion concerning manual and remote control of the instrument, refer to your analyzer's
help system or user manual. A more detailed description of the hardware connectors
and interfaces is also part of the help system or user manual.
Risk of injury due to disregarding safety information
Observe the information on appropriate operating conditions provided in the data sheet
to prevent personal injury or damage to the instrument. Read and observe the basic
safety instructions provided with the instrument, in addition to the safety instructions in
the following sections. In particular:
●Do not open the instrument casing.
Risk of instrument damage due to inappropriate operating conditions
An unsuitable operating site or test setup can damage the instrument and connected
devices. Before switching on the instrument, observe the information on appropriate
operating conditions provided in the data sheet. In particular, ensure the following:
●All fan openings are unobstructed and the airflow perforations are unimpeded. The
minimum distance from the wall is 10 cm.

Unpacking and Checking the Instrument

Putting the Analyzer into Operation
R&S® ZNB/ZNBT
12Getting Started 1316.0062.02 ─ 26
Packing material
Retain the original packing material. If the instrument needs to be transported or ship-
ped later, you can use the material to protect the control elements and connectors.
Risk of injury during transportation
The carrying handles at the front and side of the casing are designed to lift or carry the
instrument. Do not apply excessive force to the handles. If a handle is ripped off, the
falling instrument can cause injury.
As the R&S ZNBT is very heavy (over 35 kg fully equipped), it must always be carried
by two people using both carrying handles to avoid personal injury or damage to the
instrument.
2.2 Positioning the Instrument
The network analyzer is designed for use under laboratory conditions, either on a
bench top or in a rack. Notice the general ambient conditions at the operating site
described under "Risk of instrument damage due to inappropriate operating conditions"
on page 11.
Instrument damage caused by electrostatic discharge
Electrostatic discharge (ESD) can damage the electronic components of the instrument
and the device under test (DUT). Electrostatic discharge is most likely to occur when
you connect or disconnect a DUT or test fixture to the instrument's test ports. To pre-
vent electrostatic discharge, use a wrist strap and cord and connect yourself to the
ground, or use a conductive floor mat and heel strap combination.
2.3 Bench Top Operation
If the analyzer is operated on a bench top, the surface must be flat. The instrument can
be used in horizontal or vertical position, standing on its feet, or with the support feet
on the bottom expanded.

R&S® ZNB/ZNBT
13Getting Started 1316.0062.02 ─ 26
Risk of injury if feet are folded out
The feet can fold in if they are not folded out completely or if the instrument is shifted.
Collapsing feet can cause injury or damage the instrument.
●Fold the feet completely in or out to ensure stability of the instrument. Never shift
the instrument when the feet are folded out.
●When the feet are folded out, do not work under the instrument or place anything
underneath.
●The feet can break if they are overloaded. The overall load on the folded-out feet
must not exceed 500 N.
2.4 Operation in a 19" Rack
The R&S ZNB/ZNBT can be mounted in 19" racks using the adapter R&S ZZA-KN5
(order number 1175.3040.00). Proceed according to the mounting instructions supplied
with the rack adapter.
Risk of instrument damage due to insufficient airflow in a rack
If the instrument is run with insufficient airflow for a longer period, the instrument over-
heats, which can disturb the operation and even cause damage.
Make sure that all fan openings are unobstructed, that the airflow perforations are
unimpeded, and that the minimum distance from the wall is 10 cm.
2.5 EMI Suppression
Electromagnetic Interference (EMI) can affect the measurement results.
To suppress generated Electromagnetic Interference:
●Use suitable shielded cables of high quality (see table below)
●Always terminate open cable ends
●Note the EMC classification in the data sheet
Regarding length and quality, the following requirements have to be met for cable that
are directly connected to the R&S ZNB/ZNBT:

2.6 Connecting the Analyzer to the AC Supply
The network analyzer is automatically adapted to the AC supply voltage, which must
be in the range of 100 V to 240 V at 50 Hz to 60 Hz. A line frequency of 400 Hz is also
supported.
The mains connector is located in the upper part of the rear panel (see Chapter 3.3,
"Rear Panel R&S ZNB", on page 33 or Chapter 3.4, "Rear Panel R&S ZNBT",
on page 35).
► Connect the network analyzer to the AC power source using the AC power cable
delivered with the instrument.
The maximum power consumption and the typical power consumption of the individual
analyzer models are listed in the data sheet.
The R&S ZNBT is protected by a fuse located below the AC power switch; see Chap-
ter 7.3, "Replacing Fuses", on page 77. There are no such fuses on the R&S ZNB.
2.7 Starting the Analyzer and Shutting Down
The AC power switch is located in the upper part of the rear panel, together with the
mains connector and the fuse drawer (R&S ZNBT only; see Chapter 3.3, "Rear Panel
R&S ZNB", on page 33 or Chapter 3.4, "Rear Panel R&S ZNBT", on page 35).
Starting the Analyzer and Shutting Down

Putting the Analyzer into Operation
R&S® ZNB/ZNBT
15Getting Started 1316.0062.02 ─ 26
To start the analyzer, proceed as follows:
1. Switch the AC power switch to position I (On).
After power-on, the analyzer automatically goes to standby or ready state, depend-
ing on the state of the standby toggle key at the front panel when the instrument
was switched off last time.
2. If necessary, press the standby toggle key on the front panel to switch the instru-
ment to ready state (R&S ZNB: green LED goes on; R&S ZNBT PWR LED turns
from amber to green).
The instrument automatically performs a system check, boots the Windows® oper-
ating system and then starts the vector network analyzer (VNA) application. If it
was terminated regularly, the VNA application restores all recall sets and instru-
ment settings of the previous analyzer session.
To shut down the analyzer, proceed as follows:
1. Press the standby key.
Pressing the standby key causes the instrument to save all loaded recall sets, to
close the VNA application, to shut down Windows®, and to go to standby state. Of
course, you can also perform these steps manually, like in any Windows session.
2. If desired, set the AC power switch to position O (Off).
Risk of data loss
It is strongly recommended to switch the analyzer to standby state before disconnect-
ing it from the AC supply. If you set the power switch to 0 while the VNA application is
still running, you lose the current settings. Moreover, loss of program data cannot be
excluded if the application is terminated improperly.
The AC power switch can be permanently on. It is recommendable, however, to switch
it off if the instrument is not used for some time. When you switch the instrument back
on, be sure to comply with the extended warm-up phase specified in the data sheet.
2.8 Standby and Ready State
R&S ZNB: The standby toggle key is located in the bottom left corner of the front
panel. In standby state, the right, amber LED is on, in ready state, the left, green LED
is on.
R&S ZNBT: The standby toggle key is located in the bottom right corner of the front
panel. In standby state, the PWR LED light is amber, in ready state it is green.
The standby power only supplies the power switch circuits and the optional oven
quartz (option R&S ZNB-B4/R&S ZNBT-B4, "OCXO Frequency Reference"). In this
Standby and Ready State

Putting the Analyzer into Operation
R&S® ZNB/ZNBT
16Getting Started 1316.0062.02 ─ 26
state, it is safe to switch the AC power off and disconnect the instrument from the
power supply. In ready state, all modules are power-supplied. When switched to ready
state, the analyzer initiates its startup procedure.
Observe the instructions for startup and shutdown in Chapter 2.7, "Starting the Ana-
lyzer and Shutting Down", on page 14.
2.9 Connecting External Accessories
The analyzer's standard PC interfaces (Monitor, USB, LAN) can be used to connect
various accessories:
●An external monitor expands/displays the Windows® desktop, which is, by default,
covered by the Vector Network Analyzer (VNA) application window in full-screen
mode.
●External keyboard and mouse enable/simplify local control, in particular manual
(GUI) operation of the VNA application.
●A printer can be used to create hard copies of the measurement diagrams and
traces from within the VNA application.
●A LAN connection can be established to access the analyzer's mass storage or
control the analyzer from an external PC.
●Instruments equipped with controller LPW11 can also be remote controlled via
USB.
For the R&S ZNBT, external monitor and mouse are required for local operation. The
R&S ZNB can be fully controlled by tapping the touchscreen and front panel keys.
2.9.1 Connecting a Monitor
A standard monitor can be connected to the DVI-D connector of the R&S ZNB/ZNBT.
No extra configuration is required.
Instruments equipped with controller LPW11 also offer a DisplayPort.

2.9.4 Connecting a Printer
A printer can be connected to any of the USB connectors. After successful installation,
it can safely be disconnected and reconnected even during measurements.
Before printing (SYSTEM > [PRINT]), the analyzer checks whether a printer is connec-
ted and turned on and whether the appropriate printer driver is installed.
Printer driver installation
If necessary, the printer driver installation is initiated using the operating system's "Add
Printer Wizard". The wizard is self-explanatory. A printer driver must be installed only
once.
A great variety of printer drivers is available on the analyzer. To obtain the complete
list, select "Control Panel" > "Hardware and Sound" > "Devices and Printers" from the
Windows® "Start" menu.

the external keyboard.
You can load updated and improved driver versions or new drivers from an installation
disk, USB memory stick or another external storage medium. Alternatively, if the ana-
lyzer is integrated in a network, you can install driver data stored in a network directory.
In either case, use the "Add Printer" wizard to complete the installation.
Printer configuration
Use the "Printer Setup" dialog of the firmware (SYSTEM > [PRINT] > "Print...") or the
Windows® printer management to configure the printer properties and printing prefer-
ences.
2.9.5 Connecting a LAN Cable
A LAN cable can be connected to the LAN connector on the rear panel of the analyzer.
To establish a LAN connection, proceed as follows:
1. Refer to Chapter 2.12.1, "Assigning an IP Address", on page 20.
2. Connect a CAT6 or CAT7 LAN cable to the LAN port.
The LAN port of the analyzer is an auto-crossover Ethernet port. You can connect it to
a network, but you can also set up a direct connection to a computer or another instru-
ment. For both connection types, you can use either crossover or straight through
(patch) cables.
The IP address information is shown in the SYSTEM > [SETUP] > "Remote Settings"
softtool tab. For the R&S ZNBT, it is also shown on the Mini display.
2.9.6 Connecting a USB Cable for Remote Control
Instruments equipped with controller LPW11 can also be remote controlled via USB. To
prepare for remote control operation, connect a suitable USB 2.0 or 3.0 cable to the
type B "USB Device" port on the rear panel of the instrument. With direct connection to
a master device, a connecting cable A-B (plug type A onto plug type B) must be used.
For more information, refer to the Remote Control chapter of your analyzer's help sys-
tem or user manual.
